The routine intra-operative use of pulse oximetry for monitoring can prevent severe thromboembolic complications in anterior surgery

[摘要] Anterior access to the lumbar spine is established for disc replacement surgery and anterior interbody fusion in the lumbar spine. The spine is accessed normally from the left side either by a transperitoneal or retroperitoneal approach through a midline or oblique skin incision. After reaching the retroperitoneum and depending on the level of exposure, the surgeon has to mobilise and retract the aorta or left common iliac artery, as well as the left common iliac vein or internal vena cava to the right lateral border to address the whole disc space. The left common iliac artery is especially stretched during intervertebral disc exposure putting it at a greater risk of adverse events. Not surprisingly, vascular adverse events like direct injuries, thrombosis and embolism are feared complications in anterior surgery. Permanent intra-operative left leg oxygen saturation surveillance via pulse oximetry can help detecting embolic situations thereby allowing immediate treatment minimising the leg ischemia or preventing limb loss.
